“…The cell performances were measured at 700 and 600°C using humidified (3% H 2 O) model syngas and dry air fed as fuel and oxidant, respectively, at a controlled gas flow rate of 50 cm 3 /min. Considering the composition of reformed model biogas, 15) the model syngas composition was maintained at H 2 / CO = 3/2 because both reactions (1) and (2) occur in biogas reforming at once.…”
